The sprocket must get a center hole Ø D (recommended tolerance: H8) and a special keyway. Then, the taper bush can get inserted into the adaptor and both parts can get inserted into the wheel. The taper bush, the sprocket and the key have to be ordered separately. * Special keyway size. ** Feather key not like DIN.
